The OnePlus 3T was recently made available worldwide and it shipped with an Oxygen OS build based on Marshmallow. However, OnePlus promised an update based on Android Nougat. It looks like Christmas presents have arrived early for OnePlus 3T users and the Oxygen OS 4.0 OTA file has been leaked on the Internet. If we look back, benchmarks were spotted for the OnePlus devices and all the results seemed to be running a build of Android 7.0. Amidst the release of the OnePlus 3T, OnePlus seems to have prioritized the update to bring the device’s software up to Nougat. This also brings the Security Patch Level to December.
Download OnePlus 3T OTA file
Note: This update can only be applied for the OnePlus 3T only if you are running the latest version of Oxygen OS 3.5.4. If not, update to Oxygen OS 3.5.4 and then install this update.
We will need to first download the OTA zip file from here. The file size approaches around 1.4GB. We recommend using a download manager to avoid any problems with the download.
Once the file has been downloaded, copy the zip file to the Internal Storage of your OnePlus 3T
Installing the OTA file
Once copied to the Internal Storage, shutdown your device and enter recovery mode. You can enter the OnePlus 3T’s recovery mode by holding the Volume Up and Power buttons to boot into recovery mode.
Once in recovery mode, select the “Install update” option and choose the OTA zip file we copied. This should start installing the Oxygen OS 4.0 update.
Android 7.0 Nougat aims to improve and fix the shortcomings of Android 6.0 Marshmallow. It includes a whole slew of features. Some of these include a redesigned notification menu, navigation bar shortcuts and overall stable performance. Direct reply, multi-window, custom DPI slider and a new settings menu are also present here.
Nougat also aims to push the Vulkan API for gaming which helps games access hardware resources much more efficiently. Games like NFS: No Limits and Vainglory implement this and have been shown a significant boost in performance and graphic fidelity.
